what kind of bulb????

[Big Ed Deline]

Im looking to replace those little bulbs that fit in the black base then twist into their socket. An example would be the kind that luminates the 25Cent sign on the glass.  OR the kind that light up the "Insert Bill" face plate.   It took me forever to figure out that I reuse the black part and just need the bulb. So does anyone know what # of bulb I need.  Also do they make an LED lights that twists in, in place of the bulb I am looking for?
 As always,  thank you for taking the time to read and reply to me.

If this is for an S-2000 the #73 is what you will need. They do have leds, I don't know the number of those. I had read that you do not want to replace the denom bulb with an led it may cause major problems.

A good substitute for he denomination lamp is on MCM electronics web site (use IGT S2000 as a search)
if you want the best solution for the ones in the BV bezel they make a LED board that can replace it www.rudydeals.com and Raz410 has them
I have the LED board for the BV and it is bright and you wont need to replace it for a very long time.
